John

John Boyd, who settled in Ireland in 1716 and bought the estate of Crosspatrick, near Killala, Co. Mayo, belonged to a branch of family whose arms were registered at the Lyon Office in 1672 (in which year registration was first compulsory) by John Boyd, Dean of the Guild of Edinburgh, recognised by the Lyon Office to be descendant of the Lords Boyd, and from his crest descended from Thomas, second son of Alexander, 3rd Lord Boyd. Burkes' Peerage also describes him as "descended of the Family of Kilmarnock."

He married and had children:

1. Alexander
2. Dennis Boyd of Carrowkelly, died November 18th 1764, and was the ancestor of the Boyds of Carrowkelly, and of Alexander Boyd who was drowned and buried at Killlala January 9, 1800. This branch is now represented by the Ormsby family.
3. James, born 1725. Rector of Erris, near Killela.
4. Jonathon, Captain 44th Regiment. His wife Martha born 1731, died February 9, 1817 and is buried at Castlebar.
5. Patrick, born 1730. Described in his Tombstone as "a man of profound mathematical knowledge, of devotion and integrity", he died 11th March, 1810 and is buried at Castlebar. It was probably his son, Charles Boyd, who aged 17 entered Trinity Colllege Dublin, 3rd July, 1769, described as a "son of Patrick Boyd, armiger."
